<h1>Orientation dialog</h1>


<p>The orientation dialog becomes visible  when the object rotation toolbar button is selected:</p>

<p align=center><img src="images/objectRotateButton.jpg"></p>
<p class=imageLabel>[Object rotation toolbar button]</p>

<p>The dialog has three distinct tabs: 
</p>



<table class=subsectionTable><tr class=subsectionTd>
  <td class=subsectionTd>
<a name="mouseRotation"></a>Mouse Rotation
</td></tr></table> 

<p align=center><img src="images/orientationDlg1.jpg"></p>
<p class=imageLabel>[Mouse rotation tab]</p>
<br>

<p>In this section of the dialog, rotation parameters of objects manipulated with the mouse can be set. See also the page on <a href="objectMovement.htm">object movement via the mouse</a>.</p>




<li><strong>Relative to world/parent frame/own frame</strong>: indicates that a mouse drag will rotate the selected object about an axis of the absolute reference frame,  the parent object reference frame, or the object's own reference frame.</li>

<li><strong>Rotation step size</strong>: the step size used when rotating the selected object with a mouse drag (see the <a href="settings.htm">user settings dialog</a> for default step sizes).  Smaller step sized can still be used during manipulation by pressing the shift-key <strong>after</strong> the mouse button was pressed down.</li>

<li><strong>Preferred axis: about X/ about Y/ about Z</strong>: indicates that a mouse drag allows rotating the selected object about a preferred axis of the reference frame selected above. Other axes can be used during manipulation by pressing the ctrl-key <strong>after</strong> the mouse button was pressed down.</li>

<p>In this section of the dialog, setting a precise object orientation can be achieved.</p>
<li><strong>Relative to world/parent frame</strong>: indicates that the indicated <a href="eulerAngles.htm">Euler angles</a> are relative to the absolute reference frame, or relative to the parent reference frame. </li>
<li><strong>Alpha / Beta / Gamma</strong>: <a href="eulerAngles.htm">Euler angles</a> of the selected object relative to the indicated reference frame (world or parent). </li>
<br>
<br>

<a name="rotation"></a>Rotation
</td></tr></table> 

<p align=center><img src="images/orientationDlg3.jpg"></p>
<p class=imageLabel>[Rotation tab]</p>
<br>

<p>In this section of the dialog, precise object rotation can be achieved.</p>
<li><strong>Relative to world/parent frame/own frame</strong>: indicates that the rotation will be relative to the absolute reference frame, relative to the parent reference frame, or relative to the object's own reference frame.
</li>

<li>Rotate<strong> around X / Y / Z</strong>: indicates the desired rotation amounts  around the x-, y- and  z-axis of the indicated reference frame (world, parent or own frame).
</li>
